1. Have /sw32 and /sw64.
2. Install fontforge in sw64. Install wine in sw32.
The wine build will fail because it builds fontforge again. It can't install because /Applications/Fink/Fontforge.app already exists.
There has been some discussion about this on IRC, but we're not quite at the level of consensus.
Would you be so kind as to post this an issue on github, too
so that Max doesn't forget about it? :-)
